The angle adjusting component is mainly used for lamps such as blackboard lamps, stage lamps and spot lamps, and the irradiation angle of the lamps is adjusted by adjusting the angle of the fixing part 1 or the adjusting part 2. The irradiation angle of the lamp can be adjusted to a preset position according to actual requirements so as to ensure that the light of the lamp can irradiate the specified position. The fixing piece 1 and the adjusting piece 2 can be connected together in a relatively rotating mode, one of the fixing piece 1 and the adjusting piece 2 is connected with the mounting surface, the other of the fixing piece 1 and the adjusting piece 2 is connected with the lamp, and the lamp can adjust the irradiation angle relative to the mounting surface through relative rotation; the mounting surface herein refers to a ceiling, a wall, a decorative panel, a lamp bracket, etc. An adjusting groove 21 and a plurality of clamping grooves 22 are formed in the adjusting piece 2, the adjusting groove 21 is an arc-shaped through groove, and the clamping grooves 22 are communicated with the adjusting groove 21; on a projection plane perpendicular to the end face of the adjusting part 2 where the clamping grooves 22 are located, the clamping grooves 22 are distributed in an arc shape by taking the rotation center of the adjusting part 2 or the fixing part 1 as a circle center; the fixing member 1 is provided with a through hole 11 corresponding to the adjusting groove 21, and after the fixing member 1 and the adjusting member 2 are assembled, the through hole 11 is communicated with the adjusting groove 21.

Under natural state, first locating piece 32 blocks in first locating hole 312, makes locating piece 31 can not slide at will in through-hole 11, and buckle 311 imbeds in draw-in groove 22 this moment, and buckle 311 supports on the terminal surface that is close to the one end of regulating part 2 in mounting 1, because buckle 311 card is established in draw-in groove 22 for mounting 1 and regulating part 2 can't rotate relatively, and the illumination angle of lamps and lanterns is fixed this moment. When the irradiation angle needs to be adjusted, the limiting member 31 is pushed from the side far from the buckle 311 to the side close to the buckle 311, at this time, the first positioning member 32 is disengaged from the first positioning hole 312 (i.e. the first positioning member 32 is no longer clamped in the first positioning hole 312), and the buckle 311 is also disengaged from the slot 22, so that the slot 22 no longer clamps the buckle 311, and the adjusting member 2 and the fixing member 1 can rotate relatively; when the adjusting clip or the fixing member 1 rotates to a required angle, the buckle 311 corresponds to another slot 22, at this time, the limiting member 31 is pulled in the opposite direction (i.e., the direction in which the buckle 311 is clamped into the slot 22), so that the buckle 311 on the limiting member 31 is clamped into the corresponding slot 22, the first positioning member 32 is clamped into the first positioning hole 312 again, the adjusting member 2 and the fixing member 1 cannot rotate relatively, the irradiation angle of the lamp is fixed, and the irradiation angle is different from the previous irradiation angle, thereby realizing the adjustment of the irradiation angle of the lamp.

For example, the angle range that the angle adjusting assembly can adjust is 60 degrees, the angle of unit adjustment is 5 degrees (that is, the angle between two adjacent slots 22 is 5 degrees), and at this time, the number of the slots 22 is 12; when the adjustable angle range is 60 degrees, if the unit adjustment angle is set to 10 degrees, the number of the card slots 22 is 6. If the angle of the unit adjustment is 5 degrees, and the range of the adjustable angle is 90 degrees, the number of the slots 22 is 18. Therefore, the number of the slots 22, the angle in front of the slots 22, and the adjustable angle range can be set according to actual requirements.
